GEORGE W. MASON, OF SHARON, PENNSYLVA WATER-EATING APPARATUS Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed December 27, 1906. Serial No. 3&9,

To all whom it may concern:

Be it known that I, Gnonon'W'. .lVIASON, a citizen of the lhuted States residing at Sharon, in the county of Merceand State of Pennsylvania, have invented certain new and useful Improvements in lVater-l leating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this spccificat-ion.

This invention relates to an improved water heating apparatus for domestic service and it consists in the certain detailsot construction end urrangement of the parts, as will be fully described hereinafter.

In the accompanying drawings;Figurc 1 is a side sectional view, partly in elevation of an ordinary household water heating tank, having arranged in connection there with, my improved heating apparatus, the same being constructed and arranged in accordance with my invention. Fig. 2 is a sectional plan view of the heating apparatus. Fig. 3 is an enlarged. detailed sectional elevation of the heating apparatus, showing the interior water chambers and means of joining the parts together. Fig. l is a central sectional elevation of the combination hot and cold water coupling, used in connection with my improved apparatus. Fig. 5 is a sectional plan View of the same, said section being taken on the line wx, of Fig. 1. Fig. 6 isa modified form of the heating apparatus, in which the same is arranged in a horizontal position. Fig. 7 is a sectional end elevation of the same.

To construct an apparatus for heating water for domestic purposes in accordance with my invention, (see Figs. 1 to 5 inclusive) I provide awater tank 1, of suitable form and. capacity and arrange the same in a vertical position, the said tank being provided. with a water inlet pipe 2, connected with a service pipe, and at the top with a hot water outlet pipe 24, leading to points or places requiring the use of hot water. Ar-

"anged beneath the tank 1 is a heater, which consists of a series of water pipes 3, arranged in the form ot a circle, wlnch are connected at the top and bottom to heads 4: and 4: by expanding the ends of thetnbes,

in a manner well known in the art. Corr neeted to the top head 4, is a (up or cover 6, which is so formed as to provide an interior chamber 8, the said cap being attached to the head 4- by bolts and a. perfect. steam tight joint made by an annular flange 12, (slightly tapering to its )eriphory,) entering a circun'iierential groove formed on the top of said. head i.

Formed at the centr-w oi the cap 6 is a. threaded opening 7 which engages with a combined hot and cold water connection 15, which is screwed into the bottom of the tank 1. This coupling cmnpriscs an annular shell 15, externally threaded, to couple with the tank and heater, and having an inner parti tion to "tor-in two passages in and 1c, the one 16 connecting the iYQtll't-l' with a hot 'water pipe 23 arranged in the interior of the tank 1 and extending: upward to a point near ll e top of the some. The other passage 18 of this coupling opens into the tank 1 at a point near the base of the same and terinmates in a threaded socket 17, in which -a pipe 14 is attached, said pipe extending downward and is coupled to the bottom cap 6 of the heater. This latter cap '1' is at tachcd to the lower bead oi the heater in the same manner as the cap o'above by the bolts 5, also forming a water chamber S) communicating with the vertically-arranged.

heating pipes The lower head i is formed w th 11v passage 10, annular in form, the cap 6 resting on an external shoulder and held by reference to Fig. 3 of the drawings. iroj icting'upwards through the passage 10, and located centrally of the heating tubes 3, is a gas burner which comprises a short section of pipe having a series of minute radial perforations for the escape of the fuel gas, which enters said burner from a service pipe 21. Surrounding the heating pipes a casing 1'9, havin a daring bottom 20, the said casing being su 'iportcd on two small rods 25, resting on the bottom head 4. and serves to confine the heat generated by the burner In operation, the tank 1 is first filled with wate from the service pipe 2, the gas ignited .90 tightly by a jam nut 11. as will be best seen at the burner 29., and m a few moments the sage l8, continuing downward through the pipe 14 and enter the lower water chamber 9,

from which point it arises upward through 3 the heating tubes 3, gathering .heat during its passage therethrough, and is discharged 5 into the tank at the top of the pipe 23, to

be led off through the pipe 2st, to points or places requiring the use of hot water. This very quickly and with small consumption of fuel.

At Figs. (Sand 7, of the drawings, I have shown a modified form of my invention, in

which the heating tubes 3 are arranged in a horizontal position, the number of said tubes being increased by one at the center, and the burner in'this modified form arranged directly beneath the heating tubes. This form of heater is almost analogous with that previously described, the same combination hot and cold water connection 15 being used, and

the circulation maintained by the water arising from the lower tubes to those above. This heater is also inclosed within a casing having removable heads 22 and a ventopening 21 at the top, which conducts the waste heat against the bottom of the tank 1.

The advantages of this construction of water heaters are many. Itcan be' operated with oil, gas or gasolene as a fuel. The arrangement of the burner with relation to the heating tubes will greatly reduce the consumption of fuel, and by actual tests with other heaters for the same purpose,- show a reduction of fuel expense of about one-half, and will heat a given quantity of water in about'the same proportion. The heating tubes may be cleaned by. simply removing one or both heads, and the construceoe, 138

tion and arrangement of the heater is such that any mechanic of ordinary ability may install the same. The heater is simple, durable and; of few parts, and with ordinary care cannot get out of order.

Various other modified forms may be made without departing from the spirit. of the invention. Therefore I do not wish to confine myself to the exact constructions, shown and described, but wish to claim all such modified forms, as would come properly within the general scope of the invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. in a water heating apparatus, the combination of a tank, an inlet for the tank, an outlet for the tank, a connect-ion for the tank having a plurality of passageways, a pipe within the tank, said pipe being in communication with one of the passageways,

.a. heating means communicating with said passageway, and a pipe connection between a second passageway of the connection for the tank and the heating means, said second passageway communicating with the interior of the tank.

2. In a water heating apparatus, the combination of a tank, an inlet for the tank, an outlet for the tank, a connection for the tank having a plurality of passageways, a heating means in communication with one of the passageways of the connection, and means connecting a second assageway of the connection and the heating means, said second passageway communicating with the interior of the tank.

In testimony whereof, I afiix my signature, in presence of two witnesses.
